I am sorry that you have not been helped yet. I just came online and saw your question
I dont show 43 as a legitimate code. I do show a 42, but it is for the cruise control system which would not cause a loss of power.
How you are retreiving codes will not pull up the P codes, which are 4 digit codes and are for the powertrain, which is what this will be related to. the codes need to be retreived with a code reader or scan tool
